One thing to comment on here. Gengar SF has a PokePower called "Fainting Spell". This BR season players tech their decks out with cards like Technical Machine Devoluter, Blazekin, Skuntank G, Uxie, etc. just to get around that pokepower. Its all very simple because 100 + poison structure = OHKO, 90 or 100 + burn tails = OHKO, 90 + Uxie = OHKO, dark 50 w/ Lake boundary + poison = OHKO, 60 + dark Uxie = OHKO, Devoluter + 80 or 50 HP = OHKO, Damage Counters = OHKO, OHKO w/ effect = OHKO. Well, all of those above things can get around Gengar so that makes Gengar bad right? Well here are the facts about Gengar:
Psy type = nice, there are alot of psy type weakness coughmachampcough
weakness = nice, dark is a minimal type but, something to worry about
resistance = cool, flygon is popular so Gengar is good there
HP = decent, 110 is pretty easy to KO w/o a Fainting Spell flip
Poke-power = excellent, free prizes are always nice
retreat = awesome, free retreat is handy
Attack 1 = donakalicious, it makes this card Tier 1
Attack 2 = powerful, can ohko anything if your opponent doesnt play their cards right
So all in all, gengar is pretty good but, what do you do about those pesky opponents who try to get around Fainting Spell flips, you can stop most of them by Unown G and Nidoqueen. Gengar + Nidoqueen + Unown G is almost unbeatable. Your opponent must try for Fainting Spell flips and you might get ahead in the game very quickly. But, wait, wouldn't gengar get some benefit from his level x?
Gengar lv.x + Gengar + Nidoqueen + Unown G = a crazy combo.
Currently, I do NOT know what Gengar Lv.X has to make Gengar better but, here are some ideas
120-160 HP (Fainting Spell just got better)
new pokepowers (maybe), new pokebodies (maybe)
maybe a new attack that makes gengar better?
New weakness, new resistance, new type (dark, colorless, idk, just ideas)????
Gengar Lv.X sounds like a great bonus that will make Gengar very good. Don't diss it until it comes out!
